PORTABLE WINDOW-DERRICK.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed December 15, 1906. Serial No. 347,981.

To all whom tt may concern:

Be it knownthat 1, WILLIAM H. BREEN, a citizen of the United States, residing at Oharlestown, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Portable Window-Derricks, of which the following is a specification.

This invention relates to improvements in portable window derricks of that class which are adapted to be clamped to window casings of a building and used to taken through the windows into and out of the building. Heretofore, in derricks of this class it has been necessary for the operator in clamping the side members to the window casing to stand on the window sill and reach far out in order to turn the nuts which operate the clamps, this being both inconvenient and dangerous, and, furthermore, when the piano or other object was raised into alinement with the window great difficulty was experienced in drawing the object through the window, owing to the lack of any support except the window sill and tackle, the difficulty of drawing the object through the window under the circumstances being well known.

It is the object of thisinvention to provide a derrick of the character described so constructed and arranged as to be easily and quickly adjusted to walls of different thickness and so that the clamps may be operated from the interior of the building, and the object is further to provide a support upon which the object may rest while the tackle is loosed and the objcct is being drawn across a window sill.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation of my improved derrick shown attached to a window casing together with a tackle supported on said derrick and a piano suspended by said derrick. Fig. 2 is a sectional elevation taken on line 22 of Fig. 1, looking toward the right in Fig. 2. Fig. 3 is a side elevation of the derrick with the building shown in elevation and broken away to save space in the drawings, the piano being shown resting partly on the window sill and partly on the swinging support. Fig. 4 is a plan section taken on line 4-4 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5, 5 are two side members whose lower ends 6, 6 are provided with shoes 7, 7 adapted to rest upon the window sill 8.. The side members 5, 5 are adapted to contact with the opposite sides 9, 9,

respectively, of a window casing 10 on the exterior faces thereof. A cross member 11 is detachably and adjustably secured to the side mmbers 5, 5 at the upper ends 12, 12, respectively, of said side members.

The upper ends 12, 12, of the side members 5, 5 are provided with brackets 13, 13 having, tongues 14, 14 adapted to engage grooves l5, 15 formed in plates 16, 16 fast to opposite ends, respectively, of the cross member 11. The brackets 13, 13 are also provided I with pins 15, 15 adapted to engage perforations 16, 16 in the cross member 11. raise or lower pianos and the like so that they may be i An eye-bolt 17 fast to the cross member 11 is adapted to support a tackle 18 com prising pulley blocks 19 and 20 and a rope 21. The hook 22 of the pulley block 20 is adapted to receive a plate 23, said plate being secured to a piano or other object 24 by means of bands or straps 25, 25 extending completely around said piano.

Two horizontally arranged rods 26, 26, preferably rectangular in cross section, are each provided near their outer ends with a row of perforations 27 and their inner ends 28, 28 are screw-threaded to receive nuts 29, 29, said nuts being provided with handles whereby they may be easily rotated. Each of the rods 26 is located in brackets 30 and 31 fast to its respective side member 5. Each of the brackets 30 is provided with a perforation 32 adapted to receive a pin 33. The pins 33 are adapted to pass through the perforations 27 of the rods 26, whereby said rods may be adjusted with relation to the side members 5, 5. Clamps 33, 33 non-rotatably mounted on the rods 26, 26 are adapted to contact with the inner faces of the Window casing 10. By rotating the nuts 29, 29 in the proper direction, the side members 5, 5 may be rigidly clamped to the window casing 10. The pins 33, 33 are preferably fastened by chains 34, 34 to their respective side members 5, 5 so that said pins may not be lost. f

The upper ends 12, 12 of the side members 5, 5 are provided with hooks 35, 35 fast thereto, respectively. Two rods 36, 36 which may be suspended from the hooks 35, 35 are adapted to support a bar 37 which passes through eyes formed in the lower ends of said rods. When the piano 24 has beenraised into aline-. ment with the window, the rods 36, 36 and the bar 37 which constitute a swinging frame may then be swung into the proper position and the piano 24 may then be allowed to rest upon the bar 37 while the tackle 18 is loosed and said piano is being drawn across the window sill 8.

By reason of the perforations 27, 27 and the pins 33, the rods 26, 26 may be easily and quickly moved with relation to their respective side members 5, 5 so that the apparatus may be adjusted to different thicknesses of walls without loss of time and by reason of the thereof, the lower ends of said members adapted to rest on the upper face of the sill of said casing, a cross member detachably and adjustably secured to said side members at or near the upper ends thereof, two horizontally arranged rods fast to said side members, respectively, extending inwardly past said casing, two nuts having screw-threaded engagement with the inner ends of said rods, respectively, and two clamps slidably mounted on said rods, respectively, each of said clamps adapted to intervene between its respective nut and the interior face of said casing, whereby said side members may be rigidly clamped to said casing.

2. A portable window derrick comprising in its construction two side members adapted to contact with opposite sides, respectively, of a window casing on the exterior faces thereof, the lower ends of said members adapted to rest on the upper face of the sill of said casing, a cross member detachably and adjustably secured to said side members at or near the upper. ends thereof, two horizontally arranged rods fast to said side members, respec tively, extending inwardly past said casing, two nuts having screw-threaded engagement with the inner ends of said rods, respectively, and two clamps slidably and nonrotatably mounted on said rods, respectively, each adapted to intervene between its respective nut and the interior face of said casing, whereby said side members may be rigidly clamped to said casing.
